The purpose of this study was to describe the CT features of Castleman disease in the abdomen and pelvis.
The most frequent appearance of abdominal or pelvic Castleman disease is of a single, well-defined enhancing mass. Smaller tumors (<5 cm) display homogeneous contrast enhancement; larger tumors (>5 cm) show heterogeneous enhancement and attenuation when correlated with central necrosis and degeneration. Calcification was seen in 31% of the cases. Castleman disease may be considered in the differential diagnosis of a discrete enhancing mass in the abdomen or pelvis.
本研究的目的是描述腹部和盆腔Castleman病的CT特征。
腹部或盆腔Castleman病最常见的表现是单个边界清晰的强化肿块。较小的肿瘤（<5 cm）表现为均匀的对比增强；较大的肿瘤（>5 cm）与中央坏死和退变相关时表现为不均匀强化和低密度。31%的病例可见钙化。在腹部或盆腔离散性强化肿块的鉴别诊断中可考虑Castleman病。
